The strategy of the Civil War for the Confederacy (the South) was to outlast the political will of the United States (the North) to continue the fighting the war by demonstrating that the war would be long and costly.
The Seven Years’ War (1756-1763) was a global conflict that spanned five continents, though it was known in America as the “French and Indian War.” After years of skirmishes between England and France in North America, England officially declared war on France in 1756, setting off what Winston Churchill later called “the first world war.” While the French, British, and Spanish battled over colonies in the New World, Frederick the Great of Prussia faced off against Austria, France, Russia and Sweden. The Seven Year’s War ended with two treaties. The Treaty of Hubertusburg granted Silesia to Prussia and enhanced Frederick the Great’s Power. The Treaty of Paris between France, Spain and Great Britain drew colonial lines largely in favor of the British, an outcome that would later influence the French to intervene in the war for American Independence.

Civilian women and men in Belgium, the north and east of France, Serbia, and parts of the Russian empire among other locales came under the control of occupying powers.
